Problem 2 (3pts) the horizontal rigid beam abcd is supported by vertical bars (1) and (2) and is loaded at points a by vertical force p = 30 kn. bar (1) is made of aluminum [e = 70 gpa] and has a cross-sectional area of 200 mm2 and a length l1 = 8.0 m. bar (2) is made of steel [e = 200 gpa] and has a crosssectional area of 300 mm2 and a length l2 = 5.0 m. assume dimensions a = 2.5 m, b = 2.0 m, and c = 1.50 m. determine the deflection of the rigid beam (a) at point a and (b) at point d.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i. e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
